Abstract
A genetically engineered strain WSJ-IA for producing isovaleryl spiramycin I. Also provided is a method for preparing the strain, comprising the steps of: (a) constructing a recombinant plasmid comprising a double gene ist-acyB2; (b) transforming the plasmid into an isovaleryl spiramycin I - producing strain to obtain the strain WSJ-IA. The level of isovaleryl spiramycin I produced by fermentation of the strain WSJ-IA is increased 1.7 times and the fermentation potency thereof increased 4.14 times in comparison with the strain exclusively comprising a single gene ist.
